FIG. 7 is a sectional view, taken on the line 7-7 of FIG. 6.

FIG. 8 is a sectional view taken on the line 88 of FIG. 7.

Referring in detail to the drawings, numeral indicates a device forinserting liners such as the liners 30 g in an outer bag 31. As shown inthe drawings, there is provided an L-shaped bracket or support member 21that includes a horizontally disposed portion 22 that is secured to asupporting table or structure 24 in any suitable manner, as forexample'by means of securing elements 23. The bracket 21 furtherincludes an upstanding or vertically disposed portion 24. Thehorizontally disposed hollow magazine or trough 21 has one end suitablysecured as by welding to the upstanding portion 25. I

The magazine 32 includes a horizontally disposed bottom wall 26,vertically disposed spaced parallel side walls 27, and spaced paralleldiametrically opposed horizontally arranged inwardly projecting gunnelsor flanges 28, their inner edges spaced from each other so as to defineor provide an elongated slot 29, FIG. 8, for a purpose to be laterdescribed.

The numeral 33 indicates the end portion of the magazine opposite theend that is secured to the bracket 21 and the end portion 33 includes anextended portion or section 34 as well as diverging or outwardly flaringwall sections 35, and there is provided an inclined bottom section 36that terminates in a flaring or inclined triangular shaped tip 37, FIG.3.

In FIG. 5 there is illustrated a completed unit 39 which consists of theouter bag 31 with a liner 30 therein, and as shown in FIG. 5, an endportion 40 of the bag is folded over and is adapted to be-stitched orsewed, as at 41. Adjacent edge portions 38 of the bag are folded overupon adjacent sections to provide a closed end formation.

In this position, the numeral 42 indicates an extended end portion ofthe inner liner 30.

From the foregoing, it will be seen that there has been provided amethod of and means for inserting liners in outer bags and in use withthe parts arranged as shown in the drawings, the magazine or trough 32is adapted to be loaded with a plurality of flexible liners 30, and theliners 30 may be made of a suitable material such as flexible plastic.

Then, with the liner 30 arranged in the magazine 32, the operator cangrasp anfouter bag 31 with the hands, as shown in dotted lines in FIG.3, and by moving the outer bag 31 with the hands 43 over the'end portion33, the bag 31 will be expanded or opened so that it can be moved fromthe dotted line position of FIG. 3 to the solid line position of FIG. 3.The fingers of the operators hands 43 can be arranged as shown in FIG.4, so as to simultaneously grip an inner liner 30 and the adjacent endportion of a bag 31 whereby the outer bag with the inner liner can beremoved from the device so that the device can then be used in thedesired manner. After removing one of the outer bags with the innerliner, an end portion 40 can be folded upon itself and sewed or stitchedas at 41 with adjacent corner portions 38 folded as in FIG. 5 to providea completed unit, which can subsequently be filled with dynamite,fertilizer, or any other material desired or required.

The parts can be made of any suitable material and in different shapesor sizes; as desired or required.

It will, therefore, be seen that there has been provided a device whichpermits liners to be inserted in bags of woven or non-woven fabrics ormaterials and wherein the liners can be inserted without damaging theliners or bags. The inner liner 30 may be made of a suitable materialsuch as polyethylene, vinyl, ex-

truded material, including paper and plastic and other fragilematerials. The outer bag 31 may be made of any suitable material such aspaper, propelyne, burlap, cotton and various laminations and coatings.

l-Ieretofore, such liners have been inserted in bags by either puttingthe. open liner over a round or square ended board and then slipping theouter bag over the inner liner, which causes the rubbing action betweenthe inner and outer bags, or else the inner liner was inserted over aboardwhich has a sheath around it with a slot in the top, and thenslipping the outer bag over the sheath. Then it was necessary to pullboth off simultaneously, and the disadvantage of this method is thatapproximately twice theamount of motion is required as compared to thepresent invention,-and in addition more time consuming, due to the tightfit of the liner against the sheath.

In accordance with the present invention, there is provided a devicethat consists of a substantially U- shaped trough or magazine 32 thathas inward facing gunnels or flanges 28. There is also provided a linerbag flat forming plate area 33 and the outer bag opening breaker tip 37.There is also provided the L-shaped back plate, bracket 21 for holdingthe device and this.

may be clamped to a suitable supporting surface and to the table 24.

When using the present invention, the magazine 32 serves as a chamberwhich holds a plurality of folded liners' 30, and the liners 30 may beinserted through the open slot 29 in the top of the magazine. Theinwardly facing gunnels or flanges 28 assure that the folded liners 30will not be abraded by the outer bag when the outer bag 31 is pushedonto the device. The flanges 28 also hold the liners in position forforming flat in the next area.

The liner bag forming plate or section 33 takes the U-shaped innermostliner 30 from the magazine and flattens it by pushing the center up'andallowing the sides to go outward as the liner is pulled forward with theouter bag at identical surface speed without chafing, as shown in thedrawings.-

The outer bag opening breaker tip 37 opens the outer bag as it is pulledonto the magazine, as shown in FIG. 3, and assures that any glue,sizing, blocking, bottom seal and the like are broken loose beforecontacting the liner bag.

The L-shaped bracket 21 serves as the back to support the magazine andthe bottom part is adapted to be connected to a table such as the table24 by means of a C clamp or the like.

In the present invention there is provided a more economical andefficient way of inserting liners in bags and for example, the presentinvention makes approximately twice the speed in accomplishing the sameresult as compared with previous methods. In addition, the presentinvention prevents liner bags from being damaged while being inserted.

As a specific example of the use of the bag, the bag may be used for adeep hole explosive container. In such bags a misfire caused by damagedliners can cost as much as $50,000.00 in the cost of drilling and usingexplosives when used as an upset charge in a strip mine, or the like.

The present invention is not limited to use with such explosives, sinceit can be used wherever liners are to be arranged in outer bags.

As shown in the drawings, initially the liners are inserted in themagazine 32, and then the outer bag 31 is placed over the magazine, andthe procedure is followed as previously described.

Although the invention'has been herein shown and described in what isconceived to be the most practical and preferred embodiment, it isrecognized that departures may be made therefrom within the scope of theinvention which is not to be limited to the details disclosed herein butis to be accorded the full scope of the claims so as to embrace any andall equivalent devices and apparatus.
